Gibson Desert

Gibson Desert covers a large dry area in the state of Western Australia and is still largely in an almost "pristine" state. It is about 155,000 square kilometres (60,000 square miles) in size, making it the 5th largest desert in Australia, after the Great Sandy, Great Victoria, Tanami and Simpson deserts. Several isolated salt-water lakes occur in the centre of the region and to the southwest a system of small lakes follow paleo-drainage features.
Rainfall in the Gibson Desert ranges from 200 mm (7.8 in) to 250 mm (9.8 in) annually, while evaporation rates are in the 3600 mm/yr range. The climate is generally hot; summer maximum temperatures rise above 40°C (104°F) whilst in winter the maximum may fall to 18°C (64°F) and minimum winter temperatures dip to 6°C (45°F).
